In the Glallerhorn mission, A Symbol of Honor, your Ghost mentions the Royalty line of launchers, including Truth, and Charlemagne. I don't know about you, but I think that the Dubious Ordnance is actually called Charlemagne Edit: Holy shit did not expect this to gain traction Edit: The line from A Symbol of Honor The Guardian proceeds to Feizel's workshop. GHOST: These look like components for their "Royalty" line of launchers: Baron, Viceroy, Charlemagne... huh. This is a bunch of development materials from Lomar's work; I think some of these designs became the Truth launcher. This is it; these components match the notations on the Gjallarhorn blueprints. We've got what we need!
